1. Safety Instructions and Responsibility 1.1 General Safety Instructions This operation manual is a significant component of the unit and includes important rules and hints about the installation, function and usage.
1.3 Installation The device is only allowed to be installed and operated within the permissible temperature range. Please ensure an adequate ventilation and avoid all direct contact between the device and hot or aggressive gases and liquids. Before installation or maintenance, the unit must be disconnected from all voltage-sources. Further it must be ensured that no danger can arise by touching the disconnected voltagesources.
2. Applications 2.1. Dual level converter RS422 or HTL 10-30V Control 1 = LOW HTL 10-30V or RS422 A, /A, B, /B, Z, /Z A, /A, B, /B, Z, /Z In1 Out1 In2 Out2 A, /A, B, /B, Z, /Z A, /A, B, /B, Z, /Z RS422 or HTL 10-30V HTL 10-30V or RS422 Control 2 = HIGH Both inputs can be individually set to either symmetric (differential) format using A, /A, B, /B, Z, /Z channels, or to asymmetric (single-ended) format using A, B, Z channels only. Acceptable input levels are RS422, TTL and HTL 10 … 30 V.
2.3. Encoder signal switcher Both inputs can be individually set to either symmetric (differential) format using A, /A, B, /B, Z, /Z channels, or to asymmetric (single-ended) format using A, B, Z channels only. Acceptable input levels are RS422, TTL and HTL 10 … 30 V. The output standard can again be selected individually for each output. The outputs provide always all signals including the inverted channels, even when no inverted signals are applied to the input.

A, B and Z may at any time also be independent single signals, e.g. from proximities, photocells etc. Since the level of every channel is selected individually (see DIL-switch), it is possible to use different levels on the inputs. Consequently it is e.g. possible to take the position information from the A, /A, B and /B channels of a RS422 encoder, but to add the corresponding Z index pulse as a HTL signal from a remote photocell With HTL signals, the switching threshold lies between 6.5 and 8 V.
4. The Front LEDs The green LED is lit as soon as a power supply voltage is applied to the unit. The yellow LED indicates the state of the Control inputs and the basic function of the unit: Yellow LED off: Control1 and Control2 are either both LOW or both HIGH at the same time. In this case the unit operates as a splitter (both outputs are connected to the same input) Yellow LED on: Control1 and Control2 have different states.
5. Switch Settings The DIL switch sets level and standard of inputs and outputs: 0=OFF 1=ON 8 7 6 DIL switch settings 5 4 3 0 0 0 (Z) (B) (A) 1 1 1 (Z) (B) (A) 0 0 0 (Z) (B) (A) 1 1 1 (Z) (B) (A) 2 1 0 Output 1: TTL / RS422 1 Output 1: HTL 0 Output 2: TTL / RS422 1 Output 2: HTL The output levels are 5 V with TTL setting and correspond to the power supply voltage with HTL setting Both, input and inverted input must be used. Levels from 2 up to 30 V are acceptable.
